[QUOTE="vibrac, post: 24747, member: 60"] Its a good carb I belive however that the key thing is the float height In Vintage racing a TT in 1 -3/16 or 32 mm is the biggest thing you can have in upto 48 except Gardner's (GP came out in 1950 stretching 49 but never 48) A good Friend lent me an 1 -1/4 Gardener It was fitted with the recomended Vincent jet and needle and tried this on the comet mid season last year on a rolling road (where else?) with a mixture analyzer once I got it right at lowish throttle/ revs it was too weak at the top. Once I got it right at top it was too rich at the bottom. I think I would need to raise the float more but without a datum to start with we ran out of time and stuck the TT back on I also used a cut down pre-monoblock chamber wich is not ideal so I would need a good remote float all available at the moment are matchbox jobs and they are far too modern Burlen don't make the old type again yet, and the hoarders have the rest so the price is too high for an experiment [/QUOTE]
